No Network on RedHat Severn Beta 1

[Q]

Hi, is anyone out there using the new Red Hat Beta Severn? My network no longer works since installing it.   In the previous version 9.0 my network worked flawlessly (indeed it worked 'out of the box', as it were). My network card is a Realtek RTL8139 card (modules 8139too and mii) and was previously well supported. I selected DHCP as my connection type as my IP address is server assigned by my ISP, but this had no effect. Something in the new version appears to have broken network connectivity. Using the supplied network configuration tools had no effect. My motherboard type is a GA-7VAXP-A Ultra with an onboard Realtek 8139 network controller. Q
